Abstract

The invention discloses a large-scale DSP parallel computing device, and aims to provide a DSP parallel computing device which is simple in development environment, good in transportability, safe and reliable. According to the technical scheme, a backboard unit utilizes a high-speed printed circuit board (PCB) wiring technology to lead out an RIO network of an installation slot to be connected with a network switching unit, and each DSP chip sub-card board carries a DDR3 chip and cooperates with a loading FLASH chip and an EEPROM chip array to achieve a parallel computing unit. The DSP chips are symmetrically distributed and connected to the two sides of the network switching unit in a linear array manner; a control unit is connected with the network switching unit through a network cable, completes network routing, dynamically distributes sub-tasks based on measurement point calculation to each calculation node, automatically distributes calculation resources to newly established tasks, automatically distributes DSP calculation resources by receiving the calculation tasks issued by a user, and completes all iterative calculations by adopting different processes or the same process.
